oneProcessing technology of soybean residue feed
Bean dregs (tofu dregs) are a type of material that combines water and has a high oil content, making it difficult to remove water. To address this characteristic, a complete set of equipment for dehydrating and drying bean dregs (tofu dregs) has been developed. First, pass the soybean residue through a dehydrator to remove most of the free water; Then the wet soybean residue containing 55-60% water enters the soybean residue dryer and undergoes rapid drying in a specially designed drying system with a dispersing device. The heat energy is fully utilized throughout the entire drying process, and the soybean residue is uniformly heated, resulting in a good color, no paste, and low energy consumption of the dried soybean residue.
2、 Mechanical structure and working principle
The soybean residue dryer mainly consists of a heat source, a feeding machine, a rotary drum, a discharging machine, an induced draft fan, an unloader, and a distribution cabinet; After dehydration, the wet soybean residue enters the dryer and is evenly dispersed and fully contacted with hot air in the dryer under the flipping of the plate uniformly distributed in the drum, which accelerates the heat and mass transfer during drying. During the drying process, the soybean residue is discharged from the drying finished product through the star shaped discharge valve in another section of the dryer under the action of the inclined plate and heat medium. In the scheme design, the characteristics of high moisture content, high protein content, and high viscosity of soybean residue were fully considered, and a series of reasonable technologies and processes were adopted to solve them, in order to ensure good drying effect.
3、 Main features
1. The degree of mechanization in drying is high, the production capacity is large, and it can operate continuously.
2. The structure is excellent, simple, the material runs smoothly through the resistance of the cylinder, and the operation is convenient.
3. Less faults, low maintenance costs, and low power consumption.
4. The product has good uniformity in drying.
5. The soybean residue drying production line adopts a special dispersing device to ensure the drying effect of the dryer.
6. Adopting a novel and unique sealing device, coupled with an effective insulation system, effectively reduces the coal consumption of the drying system
7. The overall system has good sealing performance and is equipped with a complete dust removal device, with no dust overflow and a good operating environment.
8. The entire drying system adopts electrical centralized control, with automatic adjustment of hot air temperature, high degree of automation, and easy operation.
